Description
Technical field
The present invention relates to a kind of anchor clamps, refer in particular to a kind of expander formula anchor clamps of thin wall component, belong to the metal cutting tool technical field.
Background technology
Along with international scientific and technological progress,, extensively adopted and application in every field owing to being gradually improved of new material, novel technique; The scientific and technological content of its product is more and more higher, specification requirement is also more and more tighter.But along with China's reform and opening-up is constantly goed deep into, international status improves year by year, and overseas-funded enterprise one after the other constantly pours in, and has brought business opportunity for undoubtedly domestic economic construction and sustainable development.
But China also is in a country in developing period, and the technology of certain fields also lags behind other areas, especially industrial foundation construction aspect, compare and the developed country that one-hundred-year history is arranged, gap is more outstanding, and dependence on import is realized so the process technology of part industry is also had to.
Yet, at nonmetallic materials (material is: micro-crystalline ceramic, glass polyester ...) when product is the thin-wall construction part processing, because above-mentioned material inherent characteristic, the pressure index extremely a little less than, in case be subjected under the influence that external force extruding/support expands, the fusion of part internal stress, irregular variation takes place in profile moment, but metamorphosis in clamping process, inevitably all can take place in product usually; And the part after the processing in case discharge or difficult " return recovery " through material stress " resilience ", causes product technology requirement, accessory size and actual processing dimension far from each other.
According to the characteristic of the structural principle and the product form processing of common apparatus (lathe), people with habitual gimmick, rely on auxiliary mould to solve during to the said goods part processing usually exactly; General core (axle) rod that adopts, form (solid-state structure) is substantially: solid, hollow, step ... etc., that its fit system can only rely on is crowded, press, fill in ... etc. method finish; Its weak point: because the structure of frock determines that frock can't be accomplished with cooperating of product to be processed part: critical (that is: zero to zero) cooperates.During close-fitting: in engagement process because of the effect of frictional force, usually the part mating surface is scratched in the dismounting collide with, weight person's torsional deformation; The pine timing: in process, then be difficult for guaranteeing every technical requirement of its product, especially more outstanding when processing thin-walled part; As accompanying drawing 1 described thin-walled processing parts; For this reason: based on above-mentioned all multifactor phenomenons that causes, how at tradition (lathe) equipment, processing to thin-walled parts, I technical staff of company passes through unique jig Design theory, novel anchor clamps structure, the processing method of science, turn to integrated, new processing method/manufacturing process with polynary.
Summary of the invention
At the technical problem of above-mentioned existence, the purpose of this invention is to provide a kind of expander formula anchor clamps of thin wall component.
Realize that technical scheme of the present invention is: a kind of expander formula anchor clamps comprise body, expander spare; Described body is a hollow; Described expander spare is arranged in the body.
Preferably, part that described expander spare cooperates with body adopts cone structure, makes things convenient for separating of expander spare and body.
Preferably, described body is that wall is to disconnect.
A kind of expander formula anchor clamps of the present invention program have following advantage: 1, because described expander formula anchor clamps adopt is " disconnections " structure, when clamping parts, changed traditional " static state " fit system; But debug gimmick by " dynamically " of two parts of anchor clamps, and make its anchor clamps slowly contact with the mating surface of workpiece, attach comprehensively until mutual, then coefficient of friction is reduced to zero; Really accomplish closely to interlock, seamless connection, realized the ultimate aim of " critical cooperation "; In actual process, guarantee technical characteristic and every index request of product, satisfied user's demand; 2, described expander formula anchor clamps, scientific utilization " grafting " technology, with two kinds of distinct materials, that is: anchor clamps and measurer combine together cleverly; Adopt directed coordinate; Especially remarkable to the processed edge of thin-walled parts; Not only make part in process, every technical parameter is protected, the uniformity, stability of product (its precision can control≤0.004mm, wall thickness only within＞the 0.08mm) all can be effectively controlled simultaneously.
